When running parsec test, it reports an error `PSA_ERROR_DATA_INVALID (-153)`. This is related to `ITS_MAX_ASSET_SIZE` configuration which is been set to 512 on the secure enclave (TF-M), which defines the max asset size and it overflows when running the parsec tests. The key is generated, but when it is asked to store via `psa_its_set` it returns `PSA_ERROR_INVALID_ARGUMENT (-135)`, which then propagates to `PSA_ERROR_DATA_INVALID (-153)` Increasing the `ITS_MAX_ASSET_SIZE` to 2048 solves this issue.
